<p style="margin-top:0;margin-bottom:0">Thanks for the feedback,
Riccardo. I understand not all versions are certified
compatible but knowing that some folks have had success helps
build some confidence. I tried building 2.8.0, the latest
from the 2.8 branch, the latest from the 2.9 branch, 2.10.2,
and the latest from master (<span>2.10.56_85_g76afb10-1). Only
the latter two succeeded.</span></p>

when you build the client should not matter if you use ldiskfs or
ZFS on the server side.<br>
For my case 2.10.1 client worked on older 2.5 Lustre server
(ldiskfs) and on newer 2.9 server (ZFS backend).<br>
I did not try anyway with 2.10.2 client yet.<br>

Not sure if you can run 2.8 on Centos 7.4. You can try to git
clone the latest source code from 2.8.* and see if it builds
on Centos 7.4<br>
